StorNext: How to Change the Setting of the PERCENT_FULL_TO_MIGRATE Environment Variable

Issue:The PERCENT_FULL_TO_MIGRATE environment variable is the percentage value used to check against to determine if a medium is full enough to be migrated. Its default value is 99.9%. This article shows how to change this value.

Symptom:During Windows startup or a StorNext File System Service restart, an error dialog appears stating:

(Critical) StorNext File System FSS 'snfs1[0]': error: Unable to open C:\Program Files\StorNext\config\snfs1.cfg: No such file or directory

Cause:This is typically caused by the removal of a file system configuration file without removing its corresponding autostart entry in the StorNext File System Startup List. (The name of the problem file system is listed twice in the error message: one is in quotes and has a number in square brackets appended to it, and the other is the name of the config file listed, minus the '.cfg' suffix.)

StorNext File System: What Does the '[Node X] Disk Stripe Group 0 is DOWN' Message Mean?

Symptom:The following message displays on a metadata controller (MDC):fsm[13492]: [ID 550974 daemon.warning] StorNext File System FSS 'FSname[0]': [Node X] Disk Stripe Group 0 is DOWN for this client.

Cause:Stripe Group 0 must contain the metadata and usually includes the journal. While the MDC must be able to access this stripe group, the client is only required to have access to disks containing data.

You can find the serial number on the back of the library on the part number-serial number label. The serial number will be a 10-digit number (for example, QP0738BDC00189 or QP0732BDC00032, as in the image below).

AML 2/E/J Libraries: How can I find the Product Serial Number?

The product serial number is located on the inside of the Controller. The S/N label appears on the upper-left side of the inside front door. The S/N label is preceded by GRAU and contains serial numbers like the following:

ValueLoader: How can I find the Product Serial Number?

NOTE: The only difference between Quantum and Certance ValueLoaders is that with Certance, you can decide to add a bar code reader later. If you do not order bar code barcode reader with a Quantum ValueLoader, it cannot be added to the same unit later.

Scalar 100 Library: How can I find the Product Serial Number?

You can find the product serial number by looking on either the lower left corner of the back of the library or on the floor inside the front door. The product serial number appears in one of the following four formats: 8D0000123, 8L0000123, 9K0000123, or 9U0000123 (for example, 9U1234A02).

Scalar 218 Library: How can I find the Product Serial Number?

You can find the product serial number on an S/N sticker placed on the back and middle towards the left of the Scalar 218 frame. The product serial number appears in the format 540000123 (for example, 54089330).

NOTE: This library configuration has no remote identification options.

NOTE: The serial number is not available from the Operator Panel display.

Scalar 224/234/424/434/448/458: How can I find the product serial number?

You can find the product serial number on an S/N sticker that is placed on the back of the library towards the middle bottom of the Scalar 458 frame. This serial number is in the format 5100123 (for example, 51029722).
